WINDOW-REGULATOR INSTALLATION.'

Application filed June 18, 1924. Serial No. 720,739.

To @ZZ- ywhom il? may conce/rn.'

Be it known that We, THOMAS P. ARCHER and ERNEST E. HETNTZ, citizens of the United States, residing at Detroit, in the county of IVayne and State of Michigan, have invented cert-ain new and useful Improven'ients in Windoiv-Regulator Installa tions, of which the following is a specification. Y Y

This invention relates to a Window regulator and has :tor its Object a WindoWre-gulator which may be detachably connected with the lifting element simply by taking oil' the Window moulding and tipp-ing the Window.

However. the connection is so arranged that when the Window' is in a vertical position the litt cannot disconnect. In other Words, when the window regulator and the sash are in their accustomed vertical positions they are locked togetheigfbut When one is tilted with respect to the other they can be easily disassen'ibled.

Referring to the drawings:

Fig. l is a. side elevation ofa coupeJ with the Window regulator and the sash installed.

Fig. 2 is a cross section through the Window post with the Windenv moulding in position.

53 shows the window" moulding removed and the Windowv tipped ior disengagement from the regulator.

Figs. at and 5 are vertical sectional vie-ws Y ot' the same character.

Fig. 6 is a fragmentary detail ot' the loottom oi' the sash and the. end ot the litt lever.

The invention here is shown in connection with the. lever type of Window regulator, but it can be used for various other types, such as the chain type, cable type,

, screw and nut type and practically any type.

It is,V however, especially Well adapted for the lever type of regulator Which. requires a track or runway on the bottom of the sash in. which runs the end of the lever.

Referring to the drawings, a. designates the lever arm which is provided on its end with a ro-ll l). The periphery of this roll is convex in cross section. This is an important factor in connection With theloiver sash channel which is provided With an inverted V groove This permits the Window sash to be tipped and disengaged from the roller, as shown in Fie'. 5 when the window moulding d has been removed. y,Preferably, however, in order to eifect-the removal the roller channel e has to be slightly sprung, T'O-r when the roller is in .an upright position, as shown in Fig. 4, the channel is slightly sprung iny order to prevent rattling as it always bears on the roller lin an ul'nightposition, so as to take up all looseness. l,

Then the' Window moulding (Z is in place itis impossible for the roller and-the channel to sepai'ate under any circumstances, hence there is no danger ot any accidental disconnection'between the parts.

Preferably the Window channel is rolled as a single strip forming the Window retaining channel and the subtended roller channel. This feature, however, is no lpart oi' this invention and is not'clain'ied in this application.

IVhat ive. claim is:

l. In a window regulator installation, the

combination of a Window guide provided with means which can be removed to permit the Window to tip, a window lift including a lifting lever, a sliding sash guided in the guide. and provided .with a. track along which the lever is Vslidable, the said lever and track being connected together so that l with means which can be removed to permit the window to tilt, a Window lift, a sliding sash provided with a depending track along which ay part of the window liftengages, the said track and the engaging part of the window lift being arranged so'tliat they lock against disassembly in all positions Where the Window is veitica'l'but they permit disassembly in all positions Where t-lie Window can be. sufficiently tilted,

In a. window regulator installation, the combination of a. Window provided with a lower sash bar having a dependent channel,

a Window lift provided with a roller that 'i runs in the channel, said channel and. the roller arranged so thatthey can be. disas- Yis in a vertice-l position. v i
